Why does the pg_search prefix not work as I expect?

Question

This is my pg_search method:

  pg_search_scope :node_search, against: [:name, :user_id, :circa, :cached_tagged_user_names, :cached_user_tag_list], using: { tsearch: { any_word: true, dictionary: :english, prefix: true} }, :associated_against => { comments: [:message], user: [:first_name, :last_name, :email], memberships: [:relation], user_tags: [:name] } 

Not prefix: true for tsearch , as docs recommends .

However, in at least one particular case, it does not work as I expect.

I have a Node object that looks like this:

 => [#<Node id: 85, name: "House Fire 2", family_tree_id: 57, user_id: 57, media_id: 228, media_type: "Video", created_at: "2015-05-15 00:20:26", updated_at: "2015-06-08 22:25:49", circa: nil, is_comment: nil, cached_votes_total: 0, cached_votes_score: 0, cached_votes_up: 0, cached_votes_down: 0, cached_weighted_score: 0, cached_weighted_total: 0, cached_weighted_average: 0.0, cached_user_tag_list: " [e-mail] , [e-mail] ", cached_num_user_tags: 2, cached_tagged_user_names: ["Daniel Marty", "Marcamus Prime"]>] 

Note the cached_user_tag_list attribute, which contains the email address: [e-mail] .

However, when I do the following searches, these are the results that I get:

Note that it returns an empty result in the danny query, but it returns the correct entries in the dan and dann query.

Given that the [e-mail] is not a danny prefix for this line?

Note that for the email address [e-mail] abc search returns the correct results, as shown below:

What could be the reason for this?

Change 1

To make things weirder, I thought it was @ could drop the prefix search, so I tested it by simply changing the cached_user_tag_list attribute from [e-mail] to [e-mail] . Then I searched for dannyk and it returned the correct result, but when I looked for danny , it still returns [] . I have no idea why.

Answer 1

You can enable :trigram search and specify a threshold value. It matches arbitrary substrings that appear anywhere in the text that is searchable. Your last code will look like this.

 pg_search_scope :node_search, against: [:name, :user_id, :circa, :cached_tagged_user_names, :cached_user_tag_list], using: { tsearch: { any_word: true, dictionary: :english, prefix: true}, :trigram => { :threshold => 0.1 } }, :associated_against => { comments: [:message], user: [:first_name, :last_name, :email], memberships: [:relation], user_tags: [:name] }
